Question

Make a simple sketch showing how you would hook wires between an ohmmeter and two resistors R1 and R2 in order to measure the resistance of the two resistors in series. What are the formulas for the total resistance of two resistors R1 and R2 in series and in parallel? (Look up the answer in your physics text, if you do not know.) Consider two resistors with resistances R1 = 100 Ohm and R2 = 200 Ohm. Compute the resistance of these two resistors in series and in parallel. Show your work! Suppose you connected two resistors in parallel to a DC power supply so that there is a voltage across the two resistors R1 and R2. Now suppose you wish to measure the current coming out of the power supply, using the DMM. Make a sketch showing how you would connect the power supply, the two resistors, and the DMM to make the desired measurement.

Explanation / Answer

multiple questions I am allowed to solve only 1 question at a time according to chegg guidelines.

5) if the resistance in series we have formula

Req = R1 + R2 + R3 .........Rn

if the resistance in parallel we have formula

Req = 1/( 1/R1 + 1/R2 + 1/R3........1/Rn)

first we will find for series :

R1 = 100 ohms R2 = 200 ohms

Req(series) = R1 + R2 = 100 + 200 = 300 OHMS ---------------------------->>>>>>>>>>>>ANSWER)

Then now for parallel :

Req(parallel) = 1/ ( 1/100 + 1/200 ) = 66.7 ohms ------------------------------>>>>>>>>>>>ANSWER)
